Pin description
Name
8 V to 15 V supply. A 220 µF bypass capacitor to GND with a 470
nF (ceramic) in parallel is recommended.
External MOS switch gate connection of the step-up converter.
Current Sense comparator input. Connected to current sensing
resistor.
Input of the linear post-regulator. The voltage on this pin is
monitored by the internal step-up controller to keep a minimum
dropout across the linear pass transistor.
RX Output to the LNB in DiSEqC 2.0 application. See truth table
for voltage selections and description on page 4.
Bidirectional data from/to I²C bus.
Clock from I²C bus.
When the TEN bit of the system register is LOW, this pin will
accept the DiSEqC code from the main μcontroller. Each section
of the LNBH221 will use this code to modulate the internally
generated 22 kHz carrier. Set to GND this pin if not used.
22 kHz tone detector input. Must be AC coupled to the DiSEqC
bus.
